## Influxer
**NOTE**: Version 0.3.x supports InfluxDB >= 0.9.0. For InfluxDB 0.8.x use [version 0.2.5](https://github.com/palkan/influxer/tree/0.2.5).
-**NOTE**: Influxer is Rails 4+ compatible!
+**NOTE**: Influxer is Rails 4+ compatible! (Rails 3.2 support is still included but no longer required to pass all the tests).
Influxer provides an ActiveRecord-style way to work with [InfluxDB](https://influxdb.com/) with many useful features, such as:
- Familar query language (use `select`, `where`, `not`, `group` etc).
- Support for Regex conditions: `where(page_id: /^home\/.*/) #=> select * ... where page_id=~/^home\/.*/`.
-- Special query methods for InfluxDB:
+- Special query methods for InfluxDB:
- `time` - group by time (e.g. `Metrics.time(:hour) => # select * ... group by time(1h)`);
- `past` - get only points for last hour/minute/whatever (e.g. `Metrics.past(:day) => # select * ... where time > now() - 1d`);
- `since` - get only points since date (e.g. `Metrics.since(Time.utc(2014,12,31)) => # select * ... where time > 1419984000s`);
- `merge` - merge series.
- Scopes support
```ruby
- class Metrics < Influxer::Metrics
- default_scope -> { time(:hour).limit(1000) }
- tags :account_id
- attributes :value
- scope :unlimited, -> { limit(nil) }
- scope :by_account, -> (id) { where(account_id: id) if id.present? }
- end
+class Metrics < Influxer::Metrics
+ default_scope -> { time(:hour).limit(1000) }
+ tags :account_id
+ attributes :value
+ scope :unlimited, -> { limit(nil) }
+ scope :by_account, ->(id) { where(account_id: id) if id.present? }
+end
- Metrics.by_account(1)
+Metrics.by_account(1)
# => select * from "metrics" group by time(1h) where account_id=1 limit 1000
- Metrics.unlimited.by_account(1).time(:week)
+Metrics.unlimited.by_account(1).time(:week)
# => select * from "metrics" group by time(1w) where account_id=1
```
- Integrate with your model:
```ruby
- class UserVisits < Influxer::Metrics
- end
+class UserVisits < Influxer::Metrics
+end
- class User < ActiveRecord::Base
- has_metrics :visits
- end
+class User < ActiveRecord::Base
+ has_metrics :visits
+end
- user = User.find(1)
- user.visits.write(page_id: 'home')
+user = User.find(1)
+user.visits.write(page_id: "home")
#=> < creates point {user_id: 1, page_id: 'home'} in 'user_visits' series >
- user.visits.where(page_id: 'home')
+user.visits.where(page_id: "home")
#=> select * from user_visits where page_id='home'
```
